comtrol to e2

im dealing with this conversion in one of the stores i service.For some reason the circuts that are set to thermostat to terminated defrost all terminate prematurely.Had to change to case temp or time to get a proper defrost. any new info yet???

The only thing I've found that may be affecting you is that you can no longer mix an input board with analog and digital inputs. Whereas a Comtrol board you can mix and match all 16 inputs they must be split into groups of 8 that are either digital or analog running on an E2. I haven't started a store conversion yet, only have test boards running at the shop.

Maybe that is why some of the fixtures are not gettng proper defrost when the termination is set to thermostat. They terminate almost 10 sec after defrost is started. they could be the dig in that are mixed and matched.hmm... what do u think
